IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 206,731, dated August6, 1878 application filed March 22, 1878.

To all whom it may concern:

Be it known that I, JULIUS HERMANN, of Oampbellsport, in the county ofFond du Lac and State of Wisconsin, have invented certain new and usefulImprovements in Spring Bed- Bottoms; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure l is a top view, Fig. 2is a side view, and Fig. 3 is an end view, of my llllpl'OVQd spring-bed.

Similar letters of reference denote corresponding parts in all thefigures.

This invention relates to certain improvements in bed-bottoms by whichelasticity, ease, and comfort are promoted; and it consists inconstructing the head and foot or slat-supportin g portions of thebed-bottom of parallel pieces, the upper ones having upwardly-projectingpins, to which the slats are fitted and confined by cross-pieces or barssuitably secured thereon, and the lower ones serving in the capacity ofsprings and provided with end springs and a central block, upon whichthe upper pieces are supported, the said lower pieces or springs beingthemselves supported upon longitudinal flat slats secured to crosspiecesresting in mortises in the bed rails or sides, substantially ashereinafter more fully set forth.

In the drawings, A A are cross-pieces, the ends of which are adapted foradjustment in mortises in the bed-rails or side pieces. T0 or upon thesecross-pieces are bolted, riveted, or otherwise secured broad, thin,longitudinal pieces or slatsB b in such amanner th. t they (the saidslats B b) will extend some distance beyond the cross-pieces A, as at b,to form springs, transversely upon which are secured similar piecesorslats G O.

The latter-mentioned parts 0 O, with the upper bars B, arranged parallelwith G O and mounted upon central blocks D, and springs to a, supportedupon the said pieces 0, constitute the head and foot or slat-supportingportions of the bed-bottom. At the head. end of the bed the springs to aare arranged two or more in number upon each side of its center tocompensate for the excess of pressure or weight at that end.

The upper bars, B B, are provided with upwardly-projecting pins d d, asindicated in dotted lines in Fig. 3, which enter apertures in the slatsC O, placed and confined thereon by the cross-bars or pieces D D,themselves tied or strapped to the bars B B, as shown in the figures.The bars B B are connected to the lower pieces, 0 O, by means of strapsor other suitable flexible connections 0 c.

From the foregoing it will be observed that,

in addition to forming the head and foot or slat-supportin g portions ofthe bed-bottom into springs, the said portions are themselves supportedupon springs, thus promoting elasticity, ease, and comfort, thedesiderata aimed at, especially in this class of inventions.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In a bed-bottom, the combination, with the slat-supportin g portions,consisting of parallel pieces 0 O, B B, having slat-securing pins 11 d,and the interposed blocks D and springs o a, of the longitudinal slats BI), having the cross-pieces A A so arranged in connection therewith asto leave the ends I) of the said slats B b unsupported, substantially asshown and described, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JULIUS HERMANN.
